How to loop through an associative array and get the key? [duplicate]
If you use array_keys(), PHP will give you an array filled with just the keys:
$keys = array_keys($arr);foreach($keys as $key) { echo($key);}Alternatively, you can do this:
foreach($arr as $key => $value) { echo($key);}
Nobody answered with regular for loop? Sometimes I find it more readable and prefer for over foreach
So here it is:
$array = array('key1' => 'value1', 'key2' => 'value2'); $keys = array_keys($array);for($i=0; $i < count($keys); ++$i) { echo $keys[$i] . ' ' . $array[$keys[$i]] . "\n";}/* prints: key1 value1 key2 value2*/
